The present inventionrelates to tobacco Emm ,i-ng pipes and is an improvement in smoking pipes wherein-the firing of the tobacco being consumed can be manually controlled. 1

The principal object offthe present invention isto provide a smoking pipehaving means therein for controlling the firing of the tobacco, which pipe. is capable of cooling the smoke thus produced, thereby condensing moistures, oils and heavy tars therefrom and which entire pipe structure can .be economically produced.

A further object of the present invention is ito provide a smoking'pipe'structure wherein the tobacco is consumed in one portion thereof,

.while the -gremaining portions of the structure remain relatively cool; and provide passageways whereby the smoke produced may r d y ontact the relatively cooled portions for cooling the smoke and condensing objectionable ingredients 20 therefrom.

,An equally important object of the present invention is to provide a smoking pipe structure having means incorporated therein for controlling the firing of the tobacco being consumed and 725 maintaining theburning portion of the tobacco within a heat-retaining chamber which is insulated from the remaining portions of the pipe structure and which pipe structure can be quickly and simply dismantled whereby all of the ele- 30 ments comprising the same can be easily and quickly cleansed from timeto time.

And a still further and equally important object of .the present invention is to. provide a pipe structure. having a tobacco stoking means incorporated therein,-a tobacco reservoir and a heat-insulating chamber, all of which can be ,guickly assembledor disassembled as desired and.

- when assembled, will automatically .correctly position themselves whereby the. pipe may func- AO tion correctly. Further objects of the present invention will .in part be pointed out in the following detailed description of the accompanying drawing and will be in part obvious from .a consideration thereof.

.Inthe drawing: 1 :Fig. l is .a side cross sectional view ofthe pipe structure according to the present invention.

v Fig, 2is an end view of the pipe structure taken on line 2-2 of Fig. 1.

' Fig. 3 is a top crosssectional viewof the bowl .portion of the presentsmoking pipe takenon line 3-3 ofFig. 1. I

Fig. 4 is an enlarged side cross sectional .detail .55 viewof a portion .of the pipe structure,v and Fig. 5 is a side cross sectional view of a tubular member forming the tobacco reservoir and which forms anelement of'the present pipe structure.

Referring now more particularly to the accompanying drawing wherein like and corresponding parts are designated 'by similar reference characters, numeral I refers to the side wall of the pipe bowl having a base 2 closing one end thereof.

Base 2 has centrally located opening 3 formed.

'therethrough and which opening 3 is stepped,

' whereby the upper portion thereof forms a recess [4 in the interior face of'base 2. The opposite or open end 5 of bowl I projects inwardly and provides "a threaded bore .therein. Portion 6 of bowl I has formed extending therefrom a tubular 5 stem 8 having a bore '9; Said bore .9 is connected with the interior of bowl I through a series of openings formed in the-upper part of portion 6. The usual smoking pipe mouthpiece I0 having a bore I I is connected to and closes the open end 'of stem '8. i

Bowl Iwith base2 and stem 8 extending therefrom are formed from a lightweight metal such as, for example, aluminum ormagnesium and in the formation thereof, are cast as one piece with openings I being subsequently formed through portion 6 byboring or othersuitable operation.

"Producing these members in this manner materially reduces the: cost thereof .and, at the same time, produces members capable of readily re- .lceiving the remainingfelements for functioning ,in the manner desired, as will be hereinafter more fully pointed out. I

Positioned within bowl I is a tubular tobacco reservoir I2 having an'annularflange I3 formed extending from the upper end thereof "and a second annular flange I4 formedextending from the lower or opposite end thereof and which is seated upon the interior face of base 2. Reservoir I2 has an'octagonal cross sectional con- 0 figuration which is formed'by a series of longitudinally. extending and angularly related side walls I5. The upper end of reservoir I2 has an annular series of openings I6 formed extending from the upper interior, edge of reservoir I2 downwardly therethrough to a point adjacent the .lower ,face of flange I3. 'Reservoir I2 with its annular flanges I3 and I4 are formed as one piece from a heat-conducting material such as a lightweight metal as, for example, aluminum or magneslum.

Seated-upon the upper face of flange I3 is the lower face of a heat-insulating tubular ring I! whose lower peripheralportion is stepped and *threaded for being .detachablypositioned within 5 lindrically-shaped control and elevating member 28, which member has a threaded bore 22 formed i through the head thereof and a chamber 23 formed extending from said head. Said elevating member 2D has a laterally extending annular.

flange 2! which is rotatablylseated within recess 4 and thereby rotatably supports member 28 longitudinally of opening 3 Flange 2! has a slightly larger diameter than the diameter of the bore of reservoir l2 and the lower face of .flange l4 slidably contacts the upper face of flange 2lf0r'retaining the flange within recess 4, while at the same time permitting the free rotation thereof.

A threaded rod 24. having a stop 25 formed at one end thereof is rotatably mounted within and extends through. chamber 23 and bore 22 and 'threadedly engages the threads of said bore 22.

A tobacco-supporting disc .2? having an o'ctagonal periphery is positioned laterally of the bore of reservoir l2 with the periphery thereof in slidable contact longitudinally of the walls IE but having the diameter or disc 21 substantially equal to the diameter of the'bore of reservoir I2, whereby the periphery of disc '2? is in a socket-like engagement with walls 25, thereby preventing the rotation of disc 27 laterally of reservoir l2. Said disc 21 has a rectangular opening formed centrally thereof and in which is positioned a similarly shaped upper end 26 of rod 2 1 and which end 26 is securely fastened to disc 21 by flattening the top portion thereof.

The elements forming'the present pipe structure are assembled afterthe tobacco-elevating members comprising control member 20, rod 24 and disc 27 are assembled. Rod 24is inserted through the open end of chamber 23 within bore 22 through which it is screwed, at which time disc 27 is mounted upon end 26 and securely fastened thereto. These assembled members are inserted within bowl l with control member 20 extending through opening 3 and flange 2i seated within recess l. Reservoir i2 is inserted within said bowl I with flange it seated upon the interior face of base 2 and the outer portion of the upper face of flange 2|. The bore of reservoir l2 will have inserted therein disc 21. Opening 3 and recess 4 will center control member 29 relative to bowl I and reservoir l2 will be similarly centered due to flange l4 contacting the lower interior face OfbOWl 5. 'Uponring ll being screwed within portion 5 of bowl i, the lower face thereof will contact the upper face of flange l3 and force reservoir i2 downwardly, whereby flange M will be sealed against the interior face of base 2 and flange 21 will be rotatably locked in position. Similarly, the upper faceof flange l 3 will be sealed against the lower face of ring ll with the bore of reservoir l2 having theopening IQ of ring ll.

extending contiguous-therefrom. A reversal of the foregoing assembling steps permits the pipe structure to be as readily and easily disassemlbled, whereby each element thereof can be readily cleansed in any manner desired without any [inaccessible porti'oiis' remaining which "would from. Also, bore '9 permits'the smokeentering tion of the't b cq m.

hinder in a thorough cleansing of all of the elements.

After the pipe structure has been assembled, tobacco is placed through opening I9 within the bore of reservoir [2 and upon the upper face of disc 21, the upper portion of the tobacco being positioned within opening I9. Upon a flame being applied to the upper portionof the tobacco within opening illjand the sIhdkQi-l drawing upon bore ii, the tobacco will be ignited due to a draft passing through the pipe structure, as indicated by the arrows of Fig. 1 of the drawing.

As the tobacco is consumed, fresh tobacco is supplied to within opening I9 from the bore of reservoir i2 by thef smoker imparting a. righthand rotation to control member 20, which causes threaded rod .24 to unscrew from within bore 22 due to the fixedconn'ection of rod 24 with disc 21, which disc 21 is prevented from rotating by walls l5 of said reservoir. The unscrewing of rod 2d advances disc 2'! upwardly within reservoir I2 and positionsthe tobacco mounted-thereon. 'I'his advancing of disc 27 is continued from time'to time in order to provide afresh supply of tobacco within opening l9 and also to position the burning portion thereof at given points within said opening l9,- which point depends upon the particular taste' of the smoker The-closerthe upper portion of the burning tobacco approaches the upper end of opening l9, the"mfore air will be supplied thereto and it has been found that various smokers desire more or less air to be supplied to the tobacco than others, depending upon their particular taste. a g

The burning portion of the tobacco is main tained at all times within'opening- 19' and the from thence through bore H to the smoker.

Ring I? being formed of a heat-insulating mate'- rial, the heat of combustion from the burning tobacco will be retained therein and not conducted to the adjacent members, bowll and reservoir #2. As the smoke passes from openings 16, it will contact the relatively cool bowl 1 and reservoir l2 and will be cooled thereby. Further, bowl i and reservoir l2 being formed from a heat-conducting material will readily conduct heat from the smoke and the temperaturatherefore,of the smoke will be appreciablylowered, whereby heavy oils, tars and moisture will be condensed therefrom and settle upon flange i4 andedue tothe positioning of openings '1, will not be permitted to pass with the smoke through said i openings 1. Stem 8 being also formed from a heat-conducting materiahwill readily cause the smoke contacting the same to be further cooled, whereby additional oils, tars and moisture will be condensed ther'e-,

from openings 7 to expandand remain therein for being gradually drawn therefrom through the relatively smaller bore I l,lwhereby the smokevis given additional time to be further cooled. 1 1 H I I lit Openings it of reservoir :IZ' will draw -air through opening is -along the walls of said opening and thereby will cause the-tobacco within openingiS to be completelyfconsurned and,-at the same time, guide the smoke froi nthe bur'ning tobacco away "from the fresh tobacco in order that the same may "not be contaminated -o'r dampened by the residue from't consumed per- The pipe structure asr'lrin des'c'ribed and-'disi5 closed is capable of considerable modification and such modifications thereof as come within the scope of the accompanying claims are deemed to be a part of the present invention.
